I don’t quite get how high definition is an alteration but okay. What, do they think the original films were shot on vhs or something? That’s a common misconception that bugs the crap out of me with ignorant people, that hi def is a new thing. Sure it’s new for HOME MEDIA but films have always been made at a high resolution, or whatever the analog term for that would be.
I have never seen this misconception except in the case of Star Wars. It’s baffling that it keeps being repeated.
There is a belief that “old” movies aren’t HD or won’t look good in HD. It’s not just Star Wars. Not sure where it comes from. The people citing it specifically about the OT are just grasping for straws at this point.
